Filter-induced Bias in Lyα Emitter Surveys: A Comparison between Standard and Tunable Filters. Gran Telescopio Canarias Preliminary Results
Lyα emitter (LAE) surveys have successfully used the excess in a narrowband filter compared to a nearby broadband image to find candidates. However, the odd spectral energy distribution (SED) of LAEs combined with the instrumental profile has important effects on the properties of the candidate samples extracted from these surveys. We investigate
